Why do CVA Muzzleloaders have a rating of 700 Kp/cm2 = 9,957 PSI on their barrels?

A Magnum Load of 3 X 50 grn.(150 grn total) pyrodex pellets or 100 grn. loose powder (FFg) has a peak PSI pressure of 25,000 to 27.000 PSI, (may be as high as 45,000 PSI?). On Jan. 24, 2007, H.P. White Laboratory Inc. tested the hardness of a CVA barrel to Rb 85, Rc 4 = 79,000 to 81,000 PSI, (depending on Hardness Chart, not all the same). H.P. White Laboratory Inc. also tested a Thompson Center Barrel to be Rc 18 = 103,000 PSI. So why does CVA have a 700Kp/cm2 9,957 PSI (Minimum rating?) stamped on their barrels. I have a CVA Eclipse 209 Magnum, I always have shot Magnum Loads with T/C 350 grn Maxi Hunters or 350 Hornady FMBs ( Power Belts) with no problems, why do they have a low rating? KP = Kiloponds. Could it be a back pressure rating? Is it an old rating system for muzzle loaders they still use today?

oh it is probably,,, a cya issue ,,, insurance thing i have shot 150 grain out of my cva wolf no prob ,,, ok thanks eddie

One of the most famous Furniture makers in England in the last 80 years is the Mouseman - Richard Thompson who was born in Kilburn, Yorkshire, England on the 7th May 1876. If you love beautiful, handmade wooden furniture that's also highly collectible, you should investigate Robert Thompson's Mouseman furniture. On any piece of Robert Thompson Furniture was carved a mouse – hence his name "The Mouseman".

The story began when one day in 1919 an offhand remark about being as poor as a church mouse, lead him to carve a mouse on the finished cornice he was working on. In that moment, a famous trademark was born - even though it wasn't registered until the 1930's.

Even though Robert Thompson adopted the mouse as his trademark, not all the furniture created in the early years had it.

The patina of the furniture, the colour and degree of adzing, the use of a specific tool to shape the timber, also aid in identifying the pieces that weren't marked with the mouse.

His mouse has changed also.

Thomson removed the front legs from the mouse design in 1930 because they tended to break off easily.

The facts the mouse has no front legs but clearly recognisable whiskers are important things to look for when you find a piece identified as Mouseman furniture for unfortunately, there are imposters. (If you're worried about fakes, check out The Vintage Mouseman. where a "Rogue's gallery" of known replicas and fakes is maintained.)

Each piece of Mouseman Furniture is truly unique. It's not made by committee. Each craftsman starts a piece of furniture and remains responsible for it from selecting the wood to carving the signature mouse.

In fact, just by looking at the pieces, most avid collectors of Robert Thompson's furniture can tell which craftsman made the piece.

Inspired by the medieval oak furnishings at Ripon and York Cathedrals, Robert Thompson became determined to spend his life bringing back the spirit of craftsmanship in English Oak, and set about teaching himself how to use traditional craft tools. He soon developed a technique of finishing the surfaces of his oak furniture with a pronounced "tooled" effect using an adze, a medieval tool which had been much used in the past for roughing out the broad shapes of ships' timbers, etc, and this still remains a feature of today's items.

Fr Paul Nevill, a former Headmaster of Ampleforth College asked Thompson to make the Ampleforth Abbey's furniture; they liked it so much that Ampleforth kept asking Thompson for more works, including the library and most of the main building. Fr Gabriel Everitt, current Headmaster, has recently asked the Mouseman company for more work. Most of Ampleforth College houses are decorated with Robert Thompson's furniture.

The "Mouseman" style was based on sound construction and a straightforward fitness for purpose, using the three basic materials of English Oak, real cowhide and wrought iron. During his working life he worked alongside architects such as Sir Giles Scott and J S Syme, who in turn have left their mark on buildings throughout the United Kingdom.

The workshop, which is now being run by his descendants includes a showroom and visitors' centre, and is located beside the Parish Church, which contains "Mouseman" Pews, fittings and other furniture. Please enter into any Search Engine The company which is now known as "Robert Thompson's Craftsmen Ltd - The Mouseman of Kilburn.". The original Robert Thompson – The Mouseman died on December 8th 1955 and is buried in the small church graveyard at Kilburn overlooking his beloved workshop, which was later extended by his two grandsons and is still in production today.

The Chinese call Britain 'The Island of Hero's' which I think sums up what we British are all about. We British are inquisitive and competitive and are always looking over the horizon to the next adventure and discovery.
